Long time follower, first time poster. I’ve recently had the “Buzzsaw” bearing repaired done on my 2014. After picking up the car and driving for a few days my normal range of 5 m/kWh has gone down to 3-3.5 m/kWh. Thus my actual mileage of 48-52 prior is now 30-32. I returned it to the dealer to know avail. Decided to purchase an OBD2 Dongle and give My Green Volt a go. It confirmed that my instant m/kWh does not go above the 3.5 mark. Tested the same device on a friends 2013 and was able to achieve 5.8-6 m/kWh on that drive. In regards to variables that can affect the above. Tire PSI is 48 Cold, 51 Hot. No A/C Use. No route change. Weather has stayed the same during this time. 90k Miles. 250+ Lifetime. I feel something is not right. Any thoughts?
